WSO TGP Nav mode cant change SP

[TomCruise]

When i´m in the RCP(WSO) and use the TGP i cant switch to the next Sequenz Poinz via press Castle Switch Down and it´s also not changing, when pushing Button 17. It only works, when i type the Sp in the scratchpad. For the AG/Radar it works finde with Castle switch.
